Yes!
Dateline is hands-down the best true crime show. 48 Hours is hit and miss lately. They do a lot of domestic violence cases, which are boring and not whodunnits.
ID has a few good shows. I prefer ones w less cheesy reenactments and the ones that interview the detectives.
My favorites are: Paula Zahn—she’s done quite a few genealogy cases. American Monster—good cases, but a lot of reenactment. Disappeared—interesting cases. It’s amazing how many people just disappear. See No Evil— one of their best shows. Cases solved by videotape. Some are rather chilling.
The downside to these shows—some feature the same cases you’ve seen on other shows. You start watching and realize you’ve seen it.
